The shepherd moon Pan orbits Saturn in the Encke gap while the A ring surrounding the gap displays wave features created by interactions between the ring particles and Saturnian moons in this image from NASA's Cassini spacecraft.

Saturn is overexposed in this image taken by NASA's Cassini spacecraft in order to show the dim rings. Pandora (below rings to the left) has been brightened by a factor of 1.3 relative to the planet and the rings to enhance its visibility.

Saturn's moon Pan, orbiting in the Encke Gap near the top of the image, casts a short shadow on the A ring in this image taken by NASA's Cassini spacecraft about six months after the planet's August 2009 equinox.

The tiny moon Pandora appears beyond the bright disk of Saturn's rings in this image taken by NASA's Cassini spacecraft. Pandora orbits outside the F ring and, in this image, is farther from Cassini than the rings are.
